SEWER CONSTRUCTION AND METHOD THEREFOR.

Application filed October 17, 1927.

My invention relates to a new and useful method of sewer construction and a novel fastening device therefor, and more particularly a fastening clip adapted for use in connection with concrete moulding and sewer 1 have therefore devised a new and useful fastening clip whereby clay plates or other vitreous material, or their equivalent, can be held in position during the process of construction until the concrete has been poured and while it sets, said clip being easy and economical to use and apply, and being cheap to manufacture.

T o the above ends, my novel clip or fastening device consists of a blank of sheet metal or the like, preferably of a rectangular or other shape, and provided with pendant end flanges, there being a longitudinal reinforcing rib in the body of said clip, as well as two aligning notches or recesses in the opposed sides thereof.

My invention further consists of a flexible element such as a wire or the like for straddling said clip and engaging the re cesses or notches in the sides thereof, the inner ends of said wire being adapted to pass through the beam or stud of the wooden concrete mould and to be engaged and tightened at their lower ends to hold the clay plate rigidly and firmly against said stud or beam.

My invention further consists in the novel method of sewer construction hereinafter described.

My invention further consists in the novel arrangement and collocation of parts l1ereinafter described and finally claimed.

For the purpose of illustrating my invention I have shown in the accompanying drawings one form thereof which is at pres- Serial No. 226,762.

out preferred by me, since the same has been found in practlce to give satisfactory and reliable results, although it is to be understood that the various instrumentalit-ies of which my invention consists can be variously arranged and organized and that my inven tron is not limited to the precise arrangementand organization of the instrumentalities as herein shown and described.

In the accompanying drawings, in which similar numerals of reference indicate cor responding parts:

Fig. 1, represents a vertical section of a concrete sewer provided with clay plates retained by a clip embodying my invention.

Fig. 52, represents a plan view of the clip, per so, the fastening element being omitted. Fig. 3, represents an end View of Fig. 2.

Fig. 1, represents a section upon the line -i--4.- 01- Fig. 2.

Fig.4, represents the fastening element employed in connect-ion with the clip shown inFigs. 1, 2, and 3.

Fig. 5, represents a plan view showing my novel clip applied for holding a plurality of clay plates in position.

Fig. 6, represents a sectional view similar to that shown in Fig. 1, with the Wooden niouldbeam or studding removed.

In the drawings, 1' designates a clip embodying my invention comprising the body portion 2, having the reinforcing rib 3, the pendant end flanges 4, and the oppositely disposed aligning notches 14:. A fastening wire or the like, comprising the straight portion 5 of a length equal to the width of the clip 1, and having the limbs 6 bent or converged inwardly and thence continued to form the pendant arms or extensions 7, is employed to hold or secure the clip 1 in position with respect to the stud or wooden mould beam 8, said extensions 7 being provided with the eyes or loops 9, and twisted as seen in Fig. 1, above which is the retaining element 10, such as a nail or the like. 11 designates a clay plate commonly employed for lining concrete sewers, said plate being ordinarily provided with the tongues 12 which interlock with the concrete 13, as will be understood from Fig. 1.

The operation is as follows:

The studs or beams 8 are arranged along the lines of the sewer tube or tunnel to be built and the clay plates forming the lining of the sewer tube are secured thereto by means of the clip 2 engaging the tongue 12 of the clay plates 11. The fastening wire is passed around the clip 2, with the portion 5 thereof straddling the clip 2 transversely, and the converging portions 6 thereof engaging the notches or recesses 14 in the body of said clip to prevent slipping. The arms 7 of the fastening wire extend through aligning holes 16 in the stud 8 and clay plate 11, and a nail or similar rigid member is inserted between the eyes or loops on the end of said arms and said stud. By twisting the eye or loop ends 9 of the arms 7 around, the length of the arms '7 is decreased and the clip 2 is held tightly against the inner surface of the tongue 12 of the clay plate 11. The concrete is then poured as at 18, and when setinterlocks with the tongues 12, and the flanges 4 also become anchored in the concrete, so that the plates 11 become integral with the concrete mould proper. The eye or loop ends are now cut or clipped and the stud or beam 8 is withdrawn. The wire is again out flush with the inner surface 17 of the plate 11 (see Fig. 6) and a sewer tube is produced which has a smooth inner lining of clay plate which is not susceptible to or affected by the corrosiveaction of acids and similar substances.

It will be apparent from Fig. 5 that one clip may be employed for holding in position', in the manner above described, a plurality of clay plates 11. Thus, by properly staggering the plates, and bringing two, three or perhaps four tongues 12 into close proximity to each other, one clip will hold all the plates in position, thus greatly reducing the cost of time, labor, and material.

\Vhile I have described my novel clip as applied to my novel method of sewer construction and to the retention of the clay plate lining for sewers, it is to be understood that the same is applicable wherever it is desired to hold similar parts in position during the pouring or setting of concrete in other constructions, or for any other temporary connection and support.

It will also be apparent that my novel clip can be manufactured and applied at a minimum cost of time, labor and material,

thus rendering the use of my clip highly advantageous and profitable.

Having thus described my invention, what I claim as new and desire to secure by Let ters Patent, is:

1. The herein described method of sewer construction, which consists in positioning a plate of vitreous material provided with tongues upon a wooden mould beam, positioning a clip upon one of said tongues, passing a fastening wire around said plate with its ends projecting through aligning holes in said plate and mould beam, twisting the bottom ends of said wire to tighten said clip against said tongue, pouring concrete upon said plate, severing the twisted ends of said wire, and lastly removing said mould beam.

2. The herein described method of sewer construction, which consists in positioning a plate of vitreous material provided with tongues upon a wooden mould beam, positioning a clip upon one of said tongues,

passing a fastening wire around said plate with its ends projecting through aligning holes in said plate and mould beam, twisting the bottom ends of said wire to tighten said clip against said tongue, pouring concrete upon said plate, severing the twisted ends of said wire, removing said mould beam, and lastly cutting the ends of said wire flush with said plate.

3. In a device of a character stated, a sewer construction, comprising a vitreous plate provided with tongues, a mould beam below said plate, a clip having pendant end flanges and a stiffening rib positioned on one of said tongues, and a fastening wire passed around said clip and through aligning holes in said plate and beam.

1. In a device of the character stated, a. plate provided with tongues and grooves, a clip supported one one of said tongues and having pendant flanges overhanging the edges of said tongue, a stiffening rib and oppositely disposed aligning recesses in its edges, a fastening device passed transversely around said clip and engaging said recesses and having its pendant ends passing through said plate, and a layer of concrete surround ing said tongues, grooves, clip and its pendant flanges.
